Abstract: In the title compound, C₂₇H₃₀N₂O₄, the pyrrolidine ring adopts a twisted conformation. The indoline ring system is almost perpendicular to the mean plane of the pyrrolidine ring, making a dihedral angle of 81.7 (8)°. In the crystal, molecules are linked into centrosymmetric dimers with graph-set motif R₂²(16) via pairs of C-HO hydrogen bonds. The terminal ethyl group of the ester group is disordered over two sets of sites, with a site-occupancy ratio of 0.587 (11):0.413 (11).
